CAN-HEAD CUTTING AND FORMING AND FLANGE-CURLING MACHINE.

receive a liquid cement or packing preparatory to double seaming the heads or covers onthe can bodies. r

' Heretofore in the 'manufacture of can heads witlf curled flanges, the can heads have beentfirst cut and formedin' a press with. suitable dies, the cutting and forming press discharging them into abasketor other.

suitable receptacle, and then the cut and formed can heads are fed into a separate machine which operates to curl or curve the edge of the straight flange inward, and thus form a channel to receive the cement or packing.v And as the can heads tend to nest and stick together, andas the flanges of the heads have sharp cut edges, it is a matter of considerable labor and difliculty and ex pense to separate and arrange the can heads for feeding one by .one into the flange curling machine.

The object of my invention is to provide a. combined can head cuttingand forming press and curling device which will operate to both automatically cut and form the can head and curl its flange as the can heads are delivered or discharged one by one from the cutting andforming dies. To practically accomplish this object or result, and herein my invention consists, I

' provide the cutting and flange forming dies of thecutting and forming press with provisions for slightly-starting or curving the can head flange and combine with the discharge chute of the press flange curling devices between-which the can headpasses as it is discharged from the press and bywhic'h the already started or slightly curved flange of each can head is curled. or curved into the required shape as the can head passes 3 between the curling devices.

The curling devices may be of any suitable kind or construction adapted to perform the flange curling function. I how- Specification of Letters Patent. Application filed October 20, 1909. Serial No. 523,600.'

ever prefer to employ for this purpose curling devices having grooved and convex faces instead of concave faces, and Iprefer that the curling devices between which the can heads pass should both be rotary ones, or in the form of rotatable flange curling disks, and I prefer to employ two pair of curling disks between-which each can headpasses successively, the latter pair being set slightly closer together than the first pair, and I prefer that the first pair of curling disks or rollers should be furnished with flat grooves or operating faces, While the latter pair should have curved grooves or operating faces, and 'thus serve to give the finished shape to the curl of the canhead flange. One of the rolls or disks of each pair is preferably made of larger diameter than the other one to cause the rolls to have a slight slipping action upon the can head rotating between them, and thus render the curling operation more ,eflicient.

My invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described and more particularly specified in the claims.

In the accompanying drawing forming a part of this specificatiomoF-igure 1 is a side elevation of a can head cutting, forming and flange curling machine embodying my invention. Fig. 2 is a detail plan view of the flange curling mechanism. Fig. 3 is an end view of the flange curling mechanism looking from line.3-3 of Fig. 2. Fig. 4: is a detailsection through the can head cutting and flange forming dies. Fig. 5 is a side elevation of. the flange curling mechanism. Fig, 6 is a detail section showing the can head as cut and formed by the dies of the press before being operated upon by the curling devices and Fig. 7 is a similar view of the can head after being operated upon by the curling devices.

In the drawing, A represents the frame.

of the. machine, B the bed of a can head cutting and forming press, 0 the cross head or plunger thereof, D D the can head cutting dies, D ID the flange forming dies of the press, the cutting and forming dies having suitable provision d d for giving the flange m'of the can'head X a slight preliminary start or curve 112 this preliminary start or curve being necessary to enable the flange vices F? F chute C are journaled on an adjustable slide adapted to perform this function, the same,

however, preferably consisting of a bevel face or shoulder a? on the lower forming die D- and a coiiperating bevel face or shoulder d on the upper cutting die 1).

C is the discharge chute of the can head cutting and forming press, the same being furnished with side guides C O between which the can heads pass, and an upper guide C beneath which the can heads pass as they are discharged from thecutting and forming dies. TheJside guides C of the discharge chute are cut out at C to receive the flange-curling devices which are arranged on each side of the can head discharge chute so that the can heads will pass between the curling devices as they pass down the chute. The flange curling: devices on opposite sides of the can head chute both preferably have convex operating faces and are both preferably in the .form of rotary disks F F1 er F F The upper pair of flange curling devices F F preferably have plain grooves or operating faces f f. The lower or finishing pair of curling devices F F preferably have curved grooves croperating faces f f The -two curling dc vices F F on one side of the discharge chute are preferably of larger diameter than the curling devices F- F on the .opposite side of the can head chute so that the peripheral speed of the former will be greater that than of the latter and thus cause the curling devices to have more or less of a slipping action-on the can head being rotated between them. This facilitates the curling action and renders more eflicient the operation of the curling devices. The shafts.

or spindles f of the rotary curling devices are preferably furnished with pulleys f", and the same are preferably driven by a belt f passing around said pulleys and around guide pulleys f f f over a pulley f on the driving shaft G of the can head cutting and forming press. The curling deon. one side of the discharge H furnished with an adjusting screw 72, for" adp stmg and regulating the pressure of the curlmg devices upon the can heads passing an d rotating between them; and one of the v cur-1111,5 devices on one side of the -.discharge vchute is also mounted in adjustable bear ing's and provided; with an independent adjusting screw 71 to enable the lower pair of curling rollers or disks to be adjusted independently of the upper pair.
